Understanding the Sun Match Engine

The Last Name Category File (personLastName*.dat)

The last name category file defines standardized versions of last names. This file is used to standardize last names when comparing person names. The Sun Match Engine uses this file when a last name field is defined for normalization or standardization in the Match Field file.

The syntax of this file is:

original-value standardized-form

You can modify or add entries in this table as needed. Table 13 describes the columns in the personLastName*.dat file.

Table 13 Last Name Category File

Column 

Description 

original-value

The original value of the last name. 

standardized-form 

The standardized version of the original value. A zero (0) in this field indicates that the original value is already in its standardized form. 

If this column contains a name instead of a zero, that name must also be listed in a different entry as an original value with a standardized form of “0”. 

Following is an excerpt from the personLastNameUS.dat file.
